Tanbara, Gunma is a very easy drive from Tokyo (170km from Meguro) 19km from Kansetsu Expressway (take your chains with you).

It is perfect for 1 day.

Tanbara is a modern medium sized, board/ski-park. There are Perfect Funparks with many jumps. The slopes are wide and very easy for beginners. Relaxed atmosphere, and very good restaurants. Try to get a Tokyu Resort Pamphlet, then you get a free 1000yen lunch in one of the restaurants.
